TO ALL WHOM IT. MAY CONCERN:

Be it known that l, ltonlcn'r KER-SHAW, oi ivorriston'n, in llluntgomery county, and State of le nnsylvanin, have invented a new and improved Mode of Delivering Yarn or Thread from Spools; and I do hereby declare that the following'is a full and exact description thereof, reference bein had to the accompanying druu'ing, and to the letters of reference marked thereon, in which Figure It represents a spool having a metallic cap or cover -placed thereon.

Figure 2 shows aplan of the same.

Figure 3 shows a sectional view of the cap or cover.

The nature of my invention consists in placing a spool, having yarn or thread thereon, upon a spindle, and covering the head (nearest the delivery point) by a cap or cover made of metal or other suitable material, said cap or cover being larger in diameter and overlapping the head or rim of said spool, so that as the yarn or thread is being unwound and delivered from the spool, which does not revolve, it cannot bear against the head of said spool, thereby avoiding variable friction, giving uniform tension, and requiring loll: power than has been required heretofore by the old system of drawing yarn from spools.

My invention is applicable to various purposes in textile manufactures, sewing machines, war ing and winding-inills or frames and other siiuilar machines where spools are used. When applied to spools med llishuttles fer weaving tape and other similar goods, the cap or cover is placed on the end of the shuttle-tongue or spindle, permitting the free delivery of the yarn therefrom, and avoiding the strain consequent; upon thej. yarn having to turn the spool, as heretofore. I have illustrated my invention, as applied to winding machines, warping-mills, 81c. I v

' A represents part of a rail or spool-frame or a winding; machine, provided with an upright spindle, B, on

n'hich is placed the spool C, having yarn or thread thereon. I) is a cap or cover, made of metal or other hard material, resting on a shoulder formed on rod B, close to the head of spool C. The heads of spool CLOVIIIC least the head nearest the point of delivery, must be inadeconiciilRas shoivn, in order to insure a true and free delivery of the thread at all times, until all is delivered, atrdto avoid its bein'g delivered except in a straight. line oran obtuse angle. The cup D is a. little larger in diameterthnn the head of spool C, and slightly overlaps the some. The lower rim or rounded edge of cap D, being made perfectly smooth, projects a little below the rim or largest part of head of spool C. E-represents a stationary metallic eye or guide, placed over the centre of spindle D and spool 0, through which-passes the yarn or thread, which may then be conducted in any way or direction to suit the purpose intended.

To obtain a constant delivery of yarn from spools without stopping the machine, I attach he OMB! 0n of the thread of a fresh or full spbel to the inner end of the thread of the spool from which the yarn is being delivered. This is ell'ected, when-tho spools are being filled with yarn or thread, by placing the loading or first end of thread into a nick or reocss formed on the inside of the lower head of spool, and causing the said and to project outside the head of spool, as shown on fig. 1 at the point marked F, so that the operator can tie the last inch of thread on a spool to the first inch of thread on a full or fresh spool.

Heretol'ore yarn has been delivered from spools by placing the same on a rod or spindle, and the yarn boilig pulled oil at a right angle compels the spool to revolve, requiring in many cases considerable poiver, and as the diameter of the yarn is constantly becoming less so is the tension of the yarn becoming greater, the spool making proportionately a greater number of revolutions to deliver the required amount of yarn in the same time. Itnill'be perceived that by the use of my improvement the spool remains stationary on its ax s, and the yarn, during delivery, comes in contact only with the smooth edge or rim of cap D, thereby requiring very little power or strain on the yarn, avoiding variable tension consequent upon the decreasing diameter of the mass of thread, as in the case of rovolving'spools, as before shown- The metallic cap D may ho,snbstituted for the head on the delivery end of spool, it being in suelrcaso made eonioabliko such head, the cap thus answering the purposes both of a cap and head. The cup D may rest on the head of spool, and in some cases may be advantageously made of glass. v

Any degree of tension required on thread used in sewing and other machines maybe obtamed by applying friction to the some, after it has passed through the metallic eye, in any of thou'clbltnon'n ways. In such case the friction can be regulated to the greatestnicety, and will be even andsteady, regardless of the plum" r yarn on the spool. I
